Question: Implementation approaches of W3C multimodal architecture?

Dear W3C mmi group!

As a PHD student which works in the area of multimodal interfaces I am 
interested in the work of the W3C group regarding the multimodal 
architecture.

As far as I can see the last working draft for multimodal architecture 
and interfaces was published on April, 14th, 2008. 
(http://www.w3.org/TR/2008/WD-mmi-arch-20080414)

Even if it is only a draft - are there any known implementation 
approaches with this architecture as a basis? (The final version will be 
out on end of 2008, right?) Any pointers to research projects (academic 
or industry) would be helpful.

Aside the W3C approach - are there any other groups who want to
define such a useful architecture for multimodal frameworks?

kind regards,
Ertl Dominik
